PURPOSE: To obtain a biosensor wherein the responsiveness of
a measuring operation in a solution under test can be measured in
a short time and to obtain its manufacturing method.

CONSTITUTION: A discrimination layer 7 which has carried and
held a biological substance is formed in such a way that it is
deposited on a partitioned space at the bottom part of a measuring
chamber 21. As a result, it can be formed in a prescribed thickness
having a small irregularity and in a wide surface area. Since the
irregularity in the thickness of the discrimination layer 7 can be
reduced, an action pole 5 and a counter pole 15 can be formed at a
narrow interval without bringing the discrimination layer 7 into
contact with the counter pole 15 when an insulating layer 1 1 is
interposed between the action pole 5 and the counter pole 15 so as
to ensure a prescribed distance. Thereby, the line of electric force of
an electric double layer which is formed between the action pole 5
and the counter pole 15 can be made short As a result, a noise
current which flows at the early stage of a measuring operation can
be converged in a short time, and the measuring time of a
substance under test can be shortened.
